(Cl. 139209) This inventionrelates to loom shuttles and more especially to the means for supportingin the shuttle body the spindle carrying the bobbin.

It is an object of my invention to provide a shuttle comprisingparticularly efiective means for securely mounting the spindle in theshuttle body, for locking it therein and for facilitating the releaseand withdrawal of the spindle after consumption of the thread carried bythe spindle.

With this end in view, I provide a spindle support fixed to the shuttlebod and I form the bottom end of the spindle in such manner that it canbe seated securely and without play in the support.

I also provide means pivoted to the shuttle body adapted to grip thespindle about to be mounted in the support, to pull the spindle downonto its seat and to lock it in the seat.

I further organize the spindle and the locking means in such manner thatmovement of the locking means in a direction counter to the lockingdirection helps disengage the spindle from its seat and therebyfacilitates its removal.

An embodiment of the present invention is illustrated diagrammaticallyby wa of example in the accompanying drawing in which:

Fig. 1 is a longitudinal section of a shuttle, with a fiat spindle aboutto be mounted therein;

Fig. 2 is a longitudinal section with the spindle mounted in workingposition;

Fig. 3 is a plan view of Fig. 2;

Fig. 4 is a view drawn to a larger scale of the seating end portion ofthe spindle as viewed from above;

Fig. 5 is a cross section on the line VV in Fig. 4, and

Fig. 6 is a horizontal sectional view of a modified form of the seatingend of the spindle.

The seating end of the flat spindle I is formed with a frusto-conicalextension II which may have a circular cross-section. This extensioniitsin a funnel-shaped seat l4 formed in the bridge piece 20 which extendsacross the cavity 2 of the shuttle body I. The extension H is providedwith a cross-bore I2 ending in lateral 1ongitudinal grooves l3, 13formed in the circumference of the extension ll.

When the spindle shall be mounted in the shuttle, the socket II isintroduced into the funnel-shaped seat M, as shown in Fig. 1, beingguided during this movement by the locking member or dip 8 whosehook-shaped end enters one of the two longitudinal grooves l3, l8 of theextension II and the cross-bore I2.

This locking member 8 is a metal clip formed like an interrogation mark,its threaded bottom end9 being fixed in an arm. 1 pivotally mounted on apin 6 which extends between the parallel shanks 3 of a horse-shoe shapedtoggle leverl mounted on an axle seated in the shuttle cavity,

' In the openfposition of the parts shown in Fig. l the guiding, lockingand releasing device comprising the toggle lever 3, 4 and the clip .8 isready to guide, grasp, pull in and lock the spindle. When the flatportion of the toggle lever is moved to rock the lever. towards theleft, the hook-end of the clip 8 enters the bore I2 of the spindleextension ll, gripping the extensionbottom 2| and ulling it towards theleft, thereby forcing the extension to firmly seat itself in thefunnel-shaped seat i4 formed in the bridge 20. When the toggle lever hasreached its end position, shownin Fig. 2, the arm abuts against aninclined face 22 on the bridge piece 20, thereby locking the threadedbottom end and the middle section 23 of the clip 8 which now rests onanother inclined face 24 of the bridge piece, ina position approachingthe horizontal, and the hook-end 25 of the clip in vertical positionwhereby the spindle extension H is held down on its funnel-shaped seatl4.

On'the other hand, if the spindle is to be removed from the shuttle,rocking the lever 4 to the right not only unlocks the extension I I, butalso pushes it away from its seat by the hook-end 25 of the clip 8exerting pressure on the top wall 26 of the bore [2 until the middlesection 23 of the clip comes to rest on the funnel-shaped seat in thebridge piece, thereby allowing the spindle extension I l to pass throughbetween the bottom 24 'of the bridge piece and its inwardly projectingparts 28 which also provide an abutment 28 for the toggle lever in itsopen position.

In the modified form shown in Fig. 6 the spindle extension I l',contrary to what is shown in Fig. 5, has .a rectangular cross-section,andso has its seat I4, whereby the spindle is prevented from turning inits seat.
